Answer 1

Answer:

Total money = 12000Rs.

First investment =x Rs.

Second investment = (12000-x)Rs.

10

X

First income X X = 12 100 10 Second income = (12000 - x) 100

10x 12

So + (12000 - x) = 1280 100 100

⇒ 10x + 144000 - 12x 128000

144000 - 128000 = 2x

16000

2 = 8000

12000 x = 4000

Investments are 8000 & 4000 Rs.
